Automatic alkali supplementing device and automatic alkali supplementing method thereof

Abstract

The invention discloses an automatic alkali supplementing device. The automatic alkali supplementing device comprises a material melting barrel, a heavy sewage pool and an automatic control system, wherein the upper end of the material melting barrel is connected with a tap water pipe; the tap water pipe is provided with a water inlet valve; a communicating pipeline is arranged between the bottompart of the material melting barrel and the heavy sewage pool; the communicating pipeline is provided with a charging control valve; the water inlet valve and the charging control valve are respectively controlled through the automatic control system, so that automatic alkali supplementing work in the heavy sewage pool can be realized. The automatic alkali supplementing device disclosed by the invention has the beneficial effects that automatic water filling work and aeration work in the material melting barrel and automatic feeding work in the heavy sewage pool can be realized through the arrangement of the material melting barrel and the control of the automatic control system, the whole process is high in automation degree, and the workload of workers is reduced; meanwhile, PH (Potential of Hydrogen) value regulation on caustic soda flakes can be carried out in the material melting barrel in advance, the stability of the PH value during a charging process is ensured, and the reaction effect in the heavy sewage pool of a sewage treatment system can be increased.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to an automatic alkali replenishment device and an automatic alkali replenishment method. Background technique [0002] At present, when the automatic treatment system of the sewage station is running at night, the adjustment pool of the sewage station needs to add alkali to adjust the pH value. This requires production personnel to add alkali in batches, and three times in one night. This will not only cause a waste of personnel, but also the effect is not good, because the pH value is relatively high when the alkali is first added to the adjustment tank, and the pH value gradually decreases as the workshop sewage continues to flow into the adjustment tank, and then the pH value rises again after adding alkali, and the pH value of the adjustment tank is adjusted overnight. The pH value of the water fluctuates in a large range, which affects the reaction effect of the re...
